Abstract (en)

[origin: WO9837983A1] On a flat panel display structure, having a raised black matrix (200) defining wells within the matrix, is deposited a non-conformal, planar layer of acrylic-containing aluminizing lacquer (208) over a layer of phosphors (206) residing within the wells of the black matrix. A planar layer of catalyst material (210) is deposited over the layer of lacquer (208). A planar aluminum layer (212) is subsequently deposited over the catalytic layer (210). Finally, a baking process is conducted at a temperature such that the lacquer layer (208) and the catalyst layer (210) are cleanly and completely evaporated. This temperature is relatively low so as not to adversely affect the reflectivity of the aluminum layer (212), damage the black matrix material (200), or induce oxidation of phosphors. A substantially planar and mirror-like aluminum surface is achieved.
